Definitions

  • AMA methacrylic acid
  • IPA isopropylamine
  • This preparation can be made according to the specific needs, operating with a large interval of quantities.
  • the preparation was made according to the procedure illustrated here below:
  • a polymeric material with self-cleaning surface was obtained by means of dispersion in mass of TiO 2 in presence of the siloxane 3-(trimethoxylsilyl) propyl methacrylate function.
  • the siloxane group allows for anchoring TiO 2 to the structure of the polymeric material, and simultaneously acts as disgregating agent.
  • cross-linked acrylic material is rather easy. Materials are simultaneously combined, with the only exception of Zn-stearate, which is added 15 minutes before the polymerization of the material. The addition of Zn-stearate is made during the last phase, in order to avoid the formation of bubbles because, in addition to being a releasing agent, Zn-stearate is also a surface-active agent.
  • the photocatalytc activity of the self-cleaning materials was controlled by measuring the following parameters:
  • methacrylic dispersion comprising a silane, and in particular 3-(trimethoxysilil) propyl methylmethacrylate that bonds the photocatalytic TiO 2 to the function -Si(OCH 3 ) 3
